Fertility and Sterility published a review on acupuncture and female fertility and found that acupuncture can reduce stress, increase blood flow to the reproductive organs and normalise menstruation and the menstrual cycle.

Since stress is known to adversely affect ovulation, it is logical that acupuncture would assist normal ovulation through the release of beta-endorphins. Indeed, recent studies have shown that women who combine acupuncture with IVF (in-vitro fertilisation) are more likely to become pregnant than those who use IVF alone, and that women who use acupuncture without any other fertility treatments were just as likely to conceive as those who used fertility drugs.
